b. twisted and valvate
c. valvate and twisted
d. vexillary and valvate​

Answer 1

Answer:

Aestivation is the arrangement of the sepals or the petals in a flower bud with relation to one another.

1) Valvate- in which the floral leaves in a whorl just touch one another at the margins without overlapping.

2) Contorted or twisted- in which the overlapping is regular in one direction so that one margin overlaps the next member on one side.

3) Imbricate- in which the margins overlap one another but not in any particular order.

4) Vexillary- in which the pos­terior vexillum overlaps the two wings which in turn again overlap the paired anterior carina.
